4x - y = 1
4x - 1 = y...y = 4x - 1
u have a slope of 4....a y int of ( 0,-1)....an x int of (1/4,0)
50779 / 590 = 86.06610169
But, you can round this to equal 86.1.
account b has 2.6% more interest than account a
First off you need to convert the numbers into mixed numbers.
1 3/7 goes to 10/7
3 2/3 goes to 11/3
Then you multiply the numerators together:
10 * 11 = 110
Do the same for the denominators:
3 * 7 = 21
Then place it into a fraction and you make the fraction positive because the signs at the start are the same:
110/21
Then you can turn it into a proper fraction:
5 5/21
